Now they know the state of each of the affected companies systems. How adept their sysops guys are, a birds eye view of their security practices. Nice move and plausible deniable too :D.

I mean how did this happen at all? Are there no checks in place @ crowdstrike? Like deploying the new update to a selected machines and check whether everything is ok, and then releasing it to the wild incrementally?

Mind boggling.
